Ordinal numbers may be written in English with numerals and letter suffixes: 1st, 2nd or 2d, 3rd or 3d, 4th, 11th, 21st, 101st, 477th, etc., with the suffix acting as an ordinal indicator. Written dates often omit the suffix, although it is nevertheless pronounced. For example: 5 November 1605 (pronounced "the fifth of November ...
In English orthography, this corresponds to the suffixes ‑st, ‑nd, ‑rd, ‑th in written ordinals (represented either on the line 1st, 2nd, 3rd, 4th or as superscript 1 st, 2 nd, 3 rd, 4 th). Also commonly encountered in Romance languages are the superscript or superior (and often underlined) masculine ordinal indicator , º , and ...
Cantor proved that the cardinality of the second number class is the first uncountable cardinality. [12] Cantor's second theorem becomes: If P ′ is countable, then there is a countable ordinal α such that P (α) = ∅. Its proof uses proof by contradiction. Let P ′ be countable, and assume there is no such α. This assumption produces two ...
More recently, they have reached into the top ten, and in 2019, for only the second time ever on the Hot 100 (the first since 1958), made it to number one. This has led to all-time records for dropping off the Hot 100, including from number one, as the songs depart regardless of their final chart positions during the season.

The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element. To convert from "value of ionization energy" to the corresponding "value of molar ionization energy", the conversion is: 1 eV = 96.48534 kJ/mol 1 kJ/mol = 0.0103642688 eV [12]
Primes that are the concatenation of the first n primes written in decimal. 2 , 23 , 2357 ( OEIS : A069151 ) The fourth Smarandache-Wellin prime is the 355-digit concatenation of the first 128 primes that end with 719.
For example, the first (K) shell has one subshell, called 1s; the second (L) shell has two subshells, called 2s and 2p; the third shell has 3s, 3p, and 3d; the fourth shell has 4s, 4p, 4d and 4f; the fifth shell has 5s, 5p, 5d, and 5f and can theoretically hold more in the 5g subshell that is not occupied in the ground-state electron ...
